Answer 2

Answer:

Option A

Step-by-step explanation:

A linear function's standard form is represented by the equation

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept(where the line crosses the y-axis).

So if a function has a slope of 7/2 which is the value of m and crosses the y-axis at 9 which is the value of b then the equation would be

[tex]y=mx+b\\y=\frac{7}{2}x+9[/tex]

So option A is our answer

The value of tan 60° in the triangle ABC is √3

Right angle triangle:

Right angle triangle have one of its angles as 90 degrees. The sides are called hypotenuse, adjacent and opposite side base on the angles.

Therefore,

ΔABC

∠C = 90°

AB = 12

BC = 6

∠B = 60°

∠A = 30°

Therefore,

tan 60° = opposite / adjacent

AC = √12² - 6² = √108 = 6√3

tan 60° = AC / BC

tan 60° = 6√3 / 6

tan 60° = √3

Answer:

arc AB = 102°arc ADB = 258°

Step-by-step explanation:

The measure of an arc is the measure of the corresponding central angle.

__

Short arc AB is shown as subtending a central angle of 102°, so the measure of arc AB is 102°.

__

The sum of arc measures in a circle is 360°, so the measure of arc ADB is 258°, the value that adds with 102° to make 360°.

Richard bought 3 pounds of bananas for $1.50. A banana weighs about 8 ounces and there are 16 ounces in a pound. At this rate, how many bananas can Richard buy for $5?

Answers

Answer:

Richard can buy 20 bananas for $5

Step-by-step explanation:

∵ Richard bought 3 pounds of bananas for $1.50

∵ 1 pound = 16 ounces

∴ 3 pounds = 3 × 16 = 48 ounces

→ That means Richard bought 48 ounces for $1.50

∴ The cost 48 ounces = $1.50

∵ A banana weighs about 8 ounces

→ Let us find 48 ounces equal to how many bananas

∵ 48 ÷ 8 = 6

∴ The 48 ounces are the weighs of 6 bananas

∴ The cost of 6 bananas = $1.50

→ To find how many bananas can he buy by $5, use the ratio method

→  Cost  :  Banana

→  1.50   :  6

→  5        :   x

→ By using cross multiplication

∵ 1.50 × x = 5 × 6

∴ 1.50x = 30

→ Divide both sides by 1.50

∴ x = 20

∵ x is the number of bananas

∴ Richard can buy 20 bananas for $5

Sally launches a rocket off of a platform. The height of the rocket, in meters, can be modeled by the function, h(x) = -5(x - 3)2 + 56, where x is in seconds. o What is the height of the platform? o What is the maximum height the rocket reaches? o How long does it take to reach this height?

Answers

Answer:

Time = 3secs

Max height = 56m

Step-by-step explanation:

Given the height reached by the rocket modeled by the equation;

h(x) = -5(x - 3)² + 56 where;

x is in seconds

The rocket velocity at its maximum height is zero.

Hence dh/dx = 0

dh/dx = 2(-5)(x-3)

dh/dx = -10(x-3)

Since dh/dx = 0

0 = -10(x-3)

0 = -10x + 30

10x = 30

x = 3secs

Hence it takes 3 secs to reach the maximum height.

Get the maximum height reached by the rocket. Substitute x = 3 into the equation given;

Recall that:

h(x) = -5(x - 3)² + 56

If x  = 3

h(3) = -5(3 - 3)² + 56

h(3) = 0 + 56

h(3) = 56

Hence the maximum height that the rocket reaches is 56m

Giving the following information:

So far, they have repaved a total of 8,747 centimeters of the road. Today, they repaved 2,138 centimeters of the road.

To calculate the number of centimeters repaved, we need to use the following formula:

Total centimeters= repaved today + previously repaved

8,747= 2,138 + previously repaved

6,609=previously repaved
